Method of Narrowband Radar Targets Sorties Identification Based on AOK Time-Frequency Analysis

Aimed at the identification problem of the non-stationary moving formation targets,a method of narrowband radar target sorties identification based on the adaptive optimal kernel(AOK) is studied,in terms of ISAR techniques and non-stationary time-frequency analytic theory,and the process and algorithm procedure for narrowband radar target sorties identification are given in this paper.Different from the traditional ways,the studied method uses Doppler differences resulted from the targets relative to the rotary motion to identify the targets,and takes the suppression of cross interference and the signal energy clustering into consideration,earning the optimal identification results.The contrast experimental results with field test data show that the method is of availability.
